Monte Bianco di Courmayeur is the South-East shoulder of Mont Blanc with 4.765 m. It is offshore to the Mont Blanc about 800 m in the direction of Courmayeur. If you look to the Mont Blanc massif from Courmayeur it seems that the Monte Bianco di Courmayeur is the top of Mont Blanc. Actually Monte Bianco di Courmayeur should be considered as the fore-summit of Mont Blanc, in fact its prominence compared to Mont Blanc is lower than thirty meters. However, due to its morphological, mountaineering and historical importance, it had been included in the main list of 4000 in the Alps. Check here the complete list of the 82 alpine Fourthousanders and the 46 minor summits: Club4000.
Monte Bianco di Courmayeur is separated from Mont Blanc by the Col Major 4720 m.
A question is if the border between Italy and France runs across Mont Blanc de Courmayeur or not. According to the latest information on the web, the border between Italy and France would run on the main summit of Mont Blanc and not on the Mont Blanc di Courmayeur; consequently this latter top would be included entirely in Italian territory. See here the latest information: The border on Mont Blanc.
The first known ascent was made on 18 August 1822 by F. Clissold with Joseph Marie Couttet and five other guides, who reached the summit descending from the main summit of Mont Blanc.
The starting point to climb Monte Bianco di Courmayeur is the town of Courmayeur in the South side of the massif.
